 Did they have SIMs in?  This 4mA drain seen by battery even when we give
 USB power is consistent with the GSM side pulling it direct from battery.

 It's from 2 months ago, we changed things around since then and can do
 with another register dump from a device that shows this behaviour.  If it
 really does show that it's a big clue.
